What type is good for slurry pumps?
Thread Content
The slurry pump in our facility keeps leaking. The technicians say there are many particles in the slurry, which causes severe wear on the pump’s seals and leads to leaks easily. I wonder if anyone has any good suggestions?
Use lined (double-shell); sealing with 32+53A(B)
Imported Fox Lawrence slurry pumps, domestically Jialite, Kole
A 32-type seal will suffice; the leakage is due to the fact that the amount of sealing oil and the pressure do not meet the required levels. We control it at 8 L/min with a pressure of 0.8 MPa
At least in the case of sealed friction pairs, it’s hard against hard, right? The flushing method depends on the conditions on site; 31(32) or 53(54) can both be considered
For centrifugal pumps, a double-shell design from Foss is better, while for positive displacement pumps, screw designs are preferable.
Our company initially used Lawrence pumps, but later, for well-known reasons, Calrit became quite widely used in China.
It is necessary to ensure a stable sealing pressure for the supply mechanical seal
